that's what happens to me... i can talk talk talk..then i try to say something important and the words go away. i call it "losing my words" and my T says it's because it's more emotionally based. i disconnect from emotional things, and then i can say whatever, but it comes out like a list or something. It has all the feeling drained out. When i try to connect to the feelings, or they come up on their own i lose my words. It's very frustrating.
